CLSM images of CT26 tumor cells after incubation with EPI/Por-PCL-PH-PEG-cRGD nanoparticles. Cellular uptake, the scale bar was 20 μm (a) and in vitro drug penetration, the scale bar was 200 μm (b) of EPI/Por-PCL-PH-PEG-cRGD and EPI/mPEG2k-PCL2k nanoparticles. Flow cytometry profiles of precursor-based nanoparticles and EPI/Por-PCL-PH-PEG-cRGD at 1 h (c) and 3 h (d)
